More than 30 years after her death, Natalie Wood's husband Robert Wagner has been named as a 'person of interest' in her 1981 drowning.

Wood's death was ruled an accidental drowning in 1981 after she fell off the family's yacht. Her body was later found floating in the water about a mile from the scene. An autopsy revealed that the actress' body had multiple bruises and abrasions.

Wood's death and the new revelations about Robert Wagner's possible involvement will be the topic of a special '48 Hours' Saturday (2/3) at 10 pm on CBS. It can be seen locally on WNEM-TV 5.
